7. A system comprising a terminal and a base station, wherein
the terminal comprises:
a receiving section that receives a medium access control (MAC) control element (CE) indicating a transmission configuration indication (TCI) state for a control resource set; and
a control section that determines, when a higher layer parameter indicating use of default beam for an uplink transmission is configured and spatial relation information applicable for the uplink transmission is not configured, whether a reference signal corresponding to the TCI state is used for a spatial relation for the uplink transmission or not, based on a time from reception of the MAC CE to the uplink transmission, and
the base station transmits the MAC CE.
